Cholla wood hasn't done anything to the pH in my tanks and I have 3 pieces in there. It just provides a good source for biofilm and being hollow shrimp and hide inside them. Not really hide well since the cholla is full of holes, but it would offer protection from fish since the holes are too small for fish to get into. Most fish anyways.
